PETROPHYSICAL EVALUATION OF WELL LOG DATA TO ANALYSE RESERVOIR PROPERTIES IN OGBA FIELD, NIGER DELTA, NIGERIA [PDF]
Geological BehaviorThis study evaluates the petrophysical characteristics of Ogba Field in the Niger Delta Basin, Nigeria, using well log data (gamma ray, resistivity, neutron, and density logs) from two wells (Ogba-1 and Ogba-2) and core data from Ogba-4ST.

Orthogonal Matching Pursuit: A Brownian Motion Analysis [PDF]
, 2011 A well-known analysis of Tropp and Gilbert shows that orthogonal matching pursuit (OMP) can recover a k-sparse n-dimensional real vector from 4 k log(n) noise-free linear measurements obtained through a random Gaussian measurement matrix with a ...

Deciphering the period spacing pattern in the oscillation spectrum of the SPB star KIC 7760680 [PDF]
, 2017 We present the analysis of KIC 7760680, the rotating Slowly Pulsating B-type star identified in the Kepler photometry. The oscillation spectrum of the star exhibits a series of 36 frequencies which are quasi-equally spaced in period. We confirm that this

A Strict Test of Stellar Evolution Models: The Absolute Dimensions of Massive Benchmark Eclipsing Binary V578 Mon [PDF]
, 2014 We determine the absolute dimensions of the eclipsing binary V578 Mon, a detached system of two early B-type stars (B0V + B1V, P$=$2.40848 d) in the star-forming region NGC 2244 of the Rosette Nebula.

Using Optimization to Obtain a Width-Independent, Parallel, Simpler, and Faster Positive SDP Solver [PDF]
, 2016 We study the design of polylogarithmic depth algorithms for approximately solving packing and covering semidefinite programs (or positive SDPs for short). This is a natural SDP generalization of the well-studied positive LP problem.

Categorical data analysis using a skewed Weibull regression model
, 2017 In this paper, we present a Weibull link (skewed) model for categorical response data arising from binomial as well as multinomial model. We show that, for such types of categorical data, the most commonly used models (logit, probit and complementary log-

On reverse hypercontractivity [PDF]
, 2012 We study the notion of reverse hypercontractivity. We show that reverse hypercontractive inequalities are implied by standard hypercontractive inequalities as well as by the modified log-Sobolev inequality.
